That prescription is a little messed up. You need to create id_dsa and on the client, as above.

But it is the client's that needs to go
into /home/user/.ssh/authorized_keys on the server, which seems to be
not what the above recipe does.

If that doesn't help, try adding -v or even -v -v to the ssh command to
see what the connection is trying to do w.r.t. your keys.
